' ioiaimI (oI."10 s 2is)' My present invention relates to the pumping art; andparticularly, because'of its light weight and extreme compactness, lends itself for general pumping uses, and which may be more specifically definedas a compact portable power pump. My present invention'is designed to meet the demand for a portable power pump of the type that-can be easily moved and carried. In the past it has been necessary to employ pumping units which could only be moved about when mounted on wheeled trucks or which were so constructed that it was necessary to use a wheeled vehicle to move them;

With my present design, however, it is possible to easily carry my entire unit from place to place as-the total weight hasbeen reduced, for certain designs, down to weigh as low as thirtyeight pounds. A unit of this type, employing a three horse powermotor, is capable of pumping thirty gallons per minute at eighty pounds pressure. This provides a very'powerfulunit' as a stream of this size'can be put to a great variety of uses, such as washing down floors and the like, wetting coal, small'sluicing operations and vide a powerful pumping unit which is characterized by its extreme compactness'and light weight.

A further object is to supply my pumping device with means which make its transportation by man power more easily accomplished.

A further object is to provide means whereby the operating conditions can be observed at all times;

A further object is to provide constructional details that will make mypumping device more suitable for the purposes intended.

Other and more specific objects will be apparent in the following descriptiontaken in con.- nection with the accompanying drawings where- Figure 1 is a top plan view of my device, certain parts being broken away to more clearly illustrate the construction.

Figure 2 is a side elevation of my device with the base member shown in section substantially along the longitudinal centre line.

Figure 3 is a side elevation with my carrying handles in their extended position.

Figure 4 is a fragmentary view showing the base of my device with the handles in their folded position.

Figure 5 is an end elevation of my base with the handles shown in section, to more easily distinguishthem from the base member itself.

Referring to 'the drawings throughout which like reference numerals indicate like parts, Numeral' 8 designates the main base member. Formed within one end of base 8 is a waterintake passage 10 which may be supplied'with the standard hose coupling fitting 12. Mounted directly abovethe ascending portion of pasof base 8. i

" At the opposite end of base 8 is a mounting pad for a gasoline motor. I have found that the most satisfactory type of motor for this purpose'is the opposed cylinder type.

This gives an unusual amount of power for the least weight consistent withsturdy construction, and further eliminates excessive vibration. I

With certain types of motors it may be desirable to recess the base as 14 to accommodate the fiy-wheel. tor and water pump as by the flange coupling The motor is mounted with the cylinders I-then directly connect my mo- 18 and 20 disposed transversely of base 8 to the end of maintaining a low centre of gravity and also to achieve compactness.

I further provide that the'carbureting system,

fold and'thegasoline supply pipe, will all be mounted below the motor within the hollow base 8, so that they will be adequately protected from injury, and further carry out my'desire for extreme compactness.

The fuel tankT is secured within the base cavity, and provided with a filling plug at 22 on the upper surface-of base 8. As a matter of convenience I make the fuel tank U shaped, which enables me then to take full advantage of the base cavity-and also to position the fillingxplug 22 at a point removed from the cylinders which, under. normal operating conditions, become very-hot, and would present quite a fire hazard were the filling plugs too close to them.

.My presentdesi gn is a modification of the form. of the portable pump shown in my copending application Serial No. 448,473, filed April 30,:19305entit1ed: Portable power pumps, and while many of'thefeatures which are common to both designs are shown in both cases, the features which I believe new and wish to specifically claim in this application are those features which make possible the extreme compactness of my present design and also those feawhich includes-the carburetor, the intake mani- Q tures which this designy-because' of its unusual construction, makes particularly desirable. One of these features is the :use of longitudinally extending handles 24, which I prefer to make in a manner that will permit .their being folded, or more properly, nested together, as for instance, as shown in Figure 4. When in this position it is easy to store or transport my device on a back packing frame.

After the motor has been in use for some time, it may be desirable to move the same short distances, as the motor may be very hot from use, it is very difficult to carry, unless some special form of carrying handles, such as I have shown, are provided.

In the form shown I have provided that handles 24 will be made of two pieces, one member 26, and the other 28. Member 28 is internally threaded at one end as at 30, to receive the externally threaded end 32, of member 26.

When it is desired to carry the hot motor the two-members are screwed together, as indicated in Figure 3 and are ready for use. The stop collars 34 and 36 and end caps 34' and 36, which are fixedly secured to members 26 and 28 respectively, prevent displacement or loss of the sections from their brackets, yet will permit the handle to be taken apart. It will be understood, I believe, that it is necessary after the brackets 38 and 40 have been bored to fit the handle that they will be again bored at an angle so thatthe handle members may be inclined as shown in Figure 4. This same result could be obtained in a little less desirable manner, by simply enlarging the bore in brackets 33 and 40. I prefer that the base of brackets 38 and 40 should be very securely bolted to frame 8, and that any adjustment to effect the taking down of handles should in no way affect the rigidness of this attachment.

Special attention is called to this owing to the fact that the base is normally made of aluminum, to the end of securing maximum rigidity with the least weight, and as aluminum is nor- .mally fairly soft metal considerable difficulty will be experienced with the screw holes enlarging unless the attachment is made very secure in the first instance. I have. supplied my pumps with solid tubing handles and have found them very satisfactory on the larger models where back portability is not so important.

Another feature that is of particular value is the use of the outwardly extending lugs 41 and 42, which are provided at the motor end of base 8.

Considerable difliculty has been experienced in the past in starting the type of motor normally used on these pumps as they are preferably of the two cycle type, and the starting of the motor is dependent on having, a balanced mixture built up within the crank case of the motor, before ignition can be accomplished.

Further, motors of thisgeneral type usually have magnetos installed as a source of igniting current, and these must be revolved at considerable speed to generate current of sufficient intensity. This is usually accomplished by having a sheave 44 secured to the fly-wheel 46. When. it is desired to start the motor, assuming, of course, that the gasoline line has been turned '"onfa short starting rqpeiis wound around sheave .44, usually aboutitwo or three turns, and then pulled sharply so as to revolve the motor at a t=relatively high speed. It has been found a great convenience during this operation to have the step lugs 41 and 42, upon which the operator can stand as he pulls upwardly on the starting rope.

As this type of motor normally operates at very high speed it is very essential that a constant flow of cooling water be provided. To provide a visual indicator I have led water discharge pipes 52 and 54 from cylinders 18 and 20 respectively to a common point of discharge as 56 where the two discharge openings are close together and may be numbered for easy inspection. I believe it will be apparent that quite a number of pipes could be so grouped together and thus make it very easy for the operator to detect any cylinders of multiple cylinder engine whose water circulating system was not working as normally intended.

While I believe it will be apparent that any suitable type of pump might be used with my device, the pump illustrated has proven unusually satisfactory. This is a modified rotor type in which the two rotor shafts 40 and 42 are geared together so that a minimum amount of Wear is experienced on the rotors themselves. With this type of pump I have experienced but little difiiculty in building up pressure of around 200 pounds per square inch. It is very necessary to have the possibility of creating this high pressure, as often it is necessary to force water through thousands of feet of hose and 7 up considerable elevation. As an example, on one occasion it was necessary to force water over a mile and a half and up several hundred feet.

into other pumps further along the line and at a higher elevation.

It is under such circumstances as this that small items, as being able to conveniently watch the flow of circulating water, becomes of vital importance as thefailure of any single pump would throw the. whole system out of use.

To further protect, particularly the Water circulating pipes of my motor, I provide a protector shield in the form of a plate 48 which is secured to bosses -on the cylinder castings.

The foregoing description and the accompany-- ing drawings clearly disclose a preferred embodiment of my invention but it will beunderstood that this disclosure is merely illustrative and that such changes in the invention may be made as are fairly within the scope and spirit of the following claim.

What I claim is:

The combination in a portable pump unit with a base having at each side thereof a pair 'of spaced, axially alined, tubular brackets of a pair of handle sections at each side of the base each section mounted to slide freely in a bracket, the sections of each pair being adapted F This was accomplished by using five of my pumps in series, the lower pumps feeding
